"It's a slow day at the Krusty Krab," and SpongeBob and Patrick are tearing the place down because Squidward tricked them into thinking it would attract customers. Mr. Krabs found this out and sentenced the two to do a super, special, secret assignment (which is just painting the whole house, but they both think it is real super, special, and secret). But Mr. Krabs tells them that the paint they are using is permanent. So if they get paint, even a drop, on anything except the wall, he will cut off their butts and place them above his fireplace. SpongeBob sees that Mr. Krabs has so many items, and tells Patrick he decides to move the items first. Patrick says that there is no need to move the items because they are not paid to move items.
Then they place a tarp, but it is just a small tarp, so they put down more tarps. SpongeBob takes out a huge brush but decides to use a tiny brush. SpongeBob takes it out, and then, six hours later, carefully paints a drop onto the wall, which begins dropping. SpongeBob (in a panic that it may get onto Mr. Krabs' First Dollar) blows on it to change direction, and blow dries it off the wall, only to have created a giant paint bubble. Patrick blows another bubble shortly after, and the two merge. SpongeBob assures that the bubble cannot get any bigger, but Patrick says "Nonsense!" and inflates the bubble, causing it to pop, covering Mr. Krabs' whole house in paint, without getting a drop on anything...except on Mr. Krabs' first dollar (the drop is able to see from the eye)!
SpongeBob tries wiping the hand stain off with his tie, but it only makes the dollar covered in paint. Then they try a couple more things to get it off, including washing it in a washing machine, spraying it, using a saw, beating it up with a club and using a computer (which Patrick just uses to smash it), but all fail. Then they decide to put another dollar on the wall. Patrick takes out a dollar from his wallet, but Patrick uses it to buy a candy bar instead. SpongeBob looks into a mirror, assuring that he shall overcome panic through strength...just as Mr. Krabs approaches his door, thus making SpongeBob's reflection leave him on his own. SpongeBob panics, but comes up with an idea to hide the stained dollar.
Mr. Krabs opens the door to his house to find the lights turned off. He turns them on and sees his house is tidy, and no bubbles. SpongeBob and Patrick are about to leave, but Mr. Krabs panics, and they think Mr. Krabs finds out about the stained dollar. They apologize, but Mr. Krabs is just surprised that they dusted his knickknacks. He panics again, SpongeBob and Patrick apologize again, but he is surprised about the painted floor molding. He panics again because he finds out that they messed up with his dollar...rama. One of his dolls in the doll collection is not upright. He says that they can go home now, but then runs into a pile of paintings where his dollar usually went and moves away each one to find SpongeBob covering the dollar.
Mr. Krabs soon takes him out of the way to find his first dollar stained and drawn by crayon (Patrick thinks Mr. Krabs will buy it). SpongeBob and Patrick are afraid to have their rear ends cut off, but he licks the dollar, and the paint (including the crayon marking) comes off of the dollar. The two are confused, and Mr. Krabs says the paint actually comes off with saliva. SpongeBob thinks that Mr. Krabs said that the paint was permanent so they would be extra careful, but Mr. Krabs said he tricked them just for fun. Shortly after, he laughs at his own jest, causing SpongeBob and Patrick to leave in disgust. But Mr. Krabs' laughter causes spit to come from his mouth and onto the paint, and realizes that he has caused the whole coat of paint to drop, assuring that he needs to learn how to "say it, not spray it."

9:05 AM: SpongeBob dips his paintbrush into the paint.
10:05 AM: After the "one hour later" time card is shown, SpongeBob appears to be sweating.
12:05 PM: After the "two hours later" time card is shown, SpongeBob's sweat becomes bigger and creates a puddle.
3:05 PM: After the "three hours later" time card is shown, Patrick says, "Can you move it along? I'm all out of time cards." SpongeBob's sweat and puddle get bigger and SpongeBob puts a drop of paint onto the wall.
In Bahasa Indonesia, Mr. Krabs said "dollar lama" when pointing to his dollarama, since there is no direct translation of "dollarama." Also, the dubber of Mr. Krabs made a mistake by saying "dollar lama," or "old dollar" in English. This confused adult viewers in Indonesia.
Also, instead of saying "super," SpongeBob and Patrick said "supper."
Running Gag: SpongeBob and Patrick trying to get the paint off the dollar.
In the Arabic version, on the network MBC3, two scenes are removed: Mr. Krabs shown relaxing with SpongeBob and Patrick's butts cut off and mounted on the wall, and Patrick washing the dollar in a washing machine.
The way that SpongeBob says "yeah" after blowing the steam with the hairdryer is the same way he says it in "Prehibernation Week."
The storyboard version has a deleted scene with SpongeBob saying "I dedicate this crash to my best friend, Squidward."
Irony: SpongeBob and Patrick could have just flipped the dollar and put it back on the wall, however considering they both are not very smart, they might not have known they could. It is also possible that Mr. Krabs may notice this, unless the design is on both sides.
Only two drops of paint (SpongeBob's single-strand brush and Patrick's bubble) are used to paint the whole room.
The scene where Patrick says "We have technology" has become a popular YouTube meme.
In the Polish dub, the episode's title is "Świeżo malowane" meaning "Wet Paint."
In the Serbian dub, the episode is called "Sveže Ofarbani" which means "Freshly Painted".
In the Bulgarian dub, the episode is called "Бояджии" which means "Painters".

In the German dub, the episode is called "Anstreicher" which means "Painter".
In the Russian dub, the episode is called "Маляры" which means "Painters".

A pink version of Mr. Krabs and a yellow version of Pearl can be seen in one of the photos.
In "Bubblestand," Patrick can't blow bubbles, but in this episode he can. This episode most likely takes place after "Bubblestand" and means that SpongeBob's bubble blowing technique worked out.
This episode is the first episode to feature a normal computer. Interestingly, this computer in Wet Painters is a CRT computer.
The episode's plot is similar to the 1997 film, Bean, where Mr. Bean ruins and devastates the Whistler's Mother portrait with ink.
Also, the exploded bubble paint that completely paints the wall without (or almost) touching decors is similar to the plot of Mr. Bean episode, Do-It-Yourself Mr. Bean, where he uses a dynamite to explode the paint can in his room where the objects are wrapped in newspaper (or almost).
One of the pictures on the wall is very similar to the paintings of the 1920-1930's Dutch painter Piet Mondrian.
The "Hanging around" Joke may be a reference to the pilot of "Full House."
Due to an error, the 1998 Klasky Csupo logo from Nickelodeon's animated TV series Rugrats was seen instead of the normal logo on airings of the episode from 2002 to 2006. See the sister episode "Krusty Krab Training Video" for more information.
The paint somehow got smeared on both sides of the dollar.
While SpongeBob and Patrick are saying "but" after the paint on dollar is removed by saliva, SpongeBob's front teeth appears to be one rather than two.
The door at Mr. Krabs' house is switching left to right. When he advises the two, he opened the door. But after, the handle switched to the right.
When SpongeBob and Patrick tried to wash the paint off the dollar with the laundry machine, the wall was not painted, and in when they used a fan, the wall was painted, and when SpongeBob used a bat on Patrick, the wall was not painted again, and when Patrick smashed the dollar with the computer, the wall was painted again. The reason why the wall was not painted, because of that early shots animate, before going outside.
The closed-captions read "(screams)" when SpongeBob yells "NOOOOOOOOOO!" The captions say "BOTH: We're sorry Mr. Krabs" when SpongeBob says "We're sorry Mr. Krabs" and Patrick says "We're so sorry."
